ALBERT HOMBRECI-IER, OF BARMENLANGERFELD, GERMANY.

Application filed December 30, 1926, Serial N0. 158,005, and in Germany July 23, 1926.

My invention relates to a spool carrier for use in connection with plaiting machines, knot-work machines, bobbin machines, and lace-making machines, especially one-thread lace-making machines in which cop spools or conical spools provided with teeth at their upper ends are employed as yarn carriers in lieu of spool with rim flanges.

The invention proper resides therein that the thread coming from the cop bobbin or from the conical bobbin guided by a head piece attached detachably to the spool carrier above the bobbin the small flap that regulates and guides the thread further being supported in said head piece.

The spring hitherto used is obviated by that new arrangement and combination of parts, and another advantage resides therein that bobbins of considerably larger diameter can be made use of, because the space required hitherto for the spring can now be filled up with yarn. The drawing-off place of the yarn that was located hitherto always outside the circumference of the bobbin is now located above the yarn and within the circumference of the bobbin. The capacity of the bobbins is enlarged whereby the number of stops of the machine as entailed by the running down of the bobbins is correspondingly reduced.

Owing to the use of cops and of conical cross bobbins the pulling otl' of the thread proceeds by far more easily and uniformly than hitherto. The thread leaves the bobbin smoothly which is useful for the ware produced. It is rendered possible to work up yarns of less tearing resistibilit-y, and be sides, the number of revolutions of the machine can be considerably increased. WVith the highspeed plaiting machines and the like as hitherto designed the possible number of revolutions cannot be utilized because of the insufliciency of the cops, as with a higher number of revolutions the threads tear by reason of the unequal pulling off and, besides, the cops have a too small amount of yarn if smaller stitches are made.

The invention is illustrated diagranunatically and by way of example on the acconr panying drawing on which Figure 1 is an axial section through a bobbin carrier designed according to this invention and carrying a conical bobbin, Figure 2 is a top view of the same, Figure 3 a view similar to Fig.

1, but showing a modification designed for cop bobbins, and Figure 4t is a top view of this modification.

On the drawing, a denotes a tubular carrier for a spool either such a, Fig. 1, intended to receive a conical bobbin, or such as Z), Fig. 3, intended to receive a cop bobbin. Detachably attached to the tubular carrier a is a head piece 0 located above the bobbin and guided vertically upon the upwardly projecting portion or end of the tubular -arrier a lateral projection of the head piece engaging a vertical slot 9 of said portion or end. The extent of the upward movement of the head piece upon the said portion or end of the carrier a is limited by a check 0 which also prevents rotatory movement of the head piece. The enlarged lowermost portion of the head piece 0 serves as carrier for the small flap d which co-operates with the ratchet teeth 6 provided at the uppermost end of the spool 11. (Fig. 1.) or Z) (Fig. 3) the efiect of the co-operation consisting in a uniform delivery of the thread from the bobbin. The thread 1L coming from the bobbin passes first through an eye 10 of the head piece, then over a guide groove i, thereafter through an eye is of the flap (Z, now through the known spring-actir ated eye Z (Z denotes the helical spring pertaining thereto) and finally away through the china eye m provided on the top of the tubular spool carrier a.

I claim:

1. A spool carrier having means for supporting a conically shaped bobbin, a head cooperating with one end of said carrier having means for conducting thread away from said bobbin, said means receiving the thread in the first instance at a point substantially at the top of the bobbin and within the circumference of the bobbin.

2. A cop carrier comprising in combination a support for a cop, a head piece cooperating with one end of said support for receiving and guiding thread from said cop, said head piece receiving the thread in the first instance at a point above and within the normal largest diameter of the cop.

3. In a device of the class described the combination comprising a support adapted to carry a conically shaped bobbin, a thread guiding head having an eye so positioned with respect to said support that when said bobbin is mounted on said support said eye 5. In a. device of the class described, the

will lie within the projection of the largest combination of a supporting means for a circumference of said bobbin. cop, a thread guiding means near one end of 4. In a device of the class described, the said supporting means and receiving thread 5 combination comprising supporting; means in the first instance at a point between the for a bobbin, a conically shaped bobbin suplargest and smallestdiameter of the cop ported by said means, a thread withdrawing used on said supporting means.

means receiving thread from said bobbin In witness whereof I have hereunto set near one end thereof and at a point which my hand.

does not fall without the largest normal cirv.

cumference of the bobbin. ALBERT HOMBRECHER.
